Abstract

This paper focuses on the hydrodynamic behaviour of bioclastic sand sampled from the cheniers of Mont-Saint-Michel bay (France). The dual behaviour of the shell fragments (low settling velocity, good resistance to unidirectional flow) should be considered as a key to understanding how this coarse material is transported across the tidal flat, and finally accumulated as cheniers. Further flume experiments including wave activity and tidal fluctuations are necessary to better quantify these complex processes
